In addition, there be provided means for indicating the extent of angular motion of the holder about one or each of its axes, whereby exact reproduction of the finished products may be facilitated, and stops may be provided to prevent any inadvertent or careless operation of the apparatus resulting in a failure to obtain the desired effect. Locking means may be provided, if desired, to retain the holder in any position, thereby permitting a plurality of exactly similar products to be expeditiously produced, when it is desired to operate the apparatus in certain manners.

It will be understood that the foregoing general description and the following detail description as well are illustrative and ex emplary of the invention but are notrestrictive thereof.

In the embodiment of my invention shown by Figs. 1 to 6 of the drawings there is provided an elongated base member 10 from which rise two upright members 11 and 12,

braced by web 13. At the upper portion of each of these members are formed alined bearings 14 and 16 respectively to receive and pivotally support the reduced end portions 17 and 18 of cradle 19, extending therebetween. A shaft 20 extends through the thickened mid-portion 21 of the cradle and at one end bears near a collar23 to which is screwed a table 22 which is securing a holder 24. At

one end of the cradle is mounted a. gear 26 rigidly secured thereto in mesh with the pinion 27 on shaft 28, which may be turned by means of hand crank 29 pinned to the shaft. Gear 26 bears between it and the upright 11, a

scale 30, graduatedin degrees or other suitable division, which cooperates with pointer 31 afiixed to upright 11 and indicates the angular position of the cradle and the holder carried thereby. On the reduced end portion 17 there are also mounted two radially extending arms 32 which may be held, in any angular position with respect to the scale and to each other, by means of set screws 34,

which bars cooperate with stop members 36 mounted at each side of the upright 11 to limit the angular movement of the cradle about its axis.

Means for indicating the angular movement of the table 22 about its axis, and with respect to the cradle are provided and here shown as a graduated scale 40 on the rear side of the cradle and fastened thereto. Two substantially radially extending spring members 42 are secured to opposite sides of a block 44, pinned to shaft 20 which cooperate with stop 46 or 47.

For turning the table about the axis formed by the shaft 20, there is provided a wheel 50 having friction surface 52 and mounted on shaft 54 received within and concentric with the reduced end portion 17 of the cradle. To the outer end of shaft 54 there is pinned a hand crank 55 by which angular movement of the table is effected. To insure constant driving engagement of the table 22 with the roller 50, a small roller 56 mounted on one end of a member 57 slidably keyed in the cradle at 58 and resiliently urged against the rear face of the table by spring 59 is provided.

A holder 24 is adapted to receive the assem bly of image forming elements 66, which may conveniently be glass plates bearing the negative and/or positive images of the original design, within the holder and between these elements and the table, the photosensitive sheet of paper or other surface which is to be transformed into the final design-bearing sheet. The image forming elements may be registered with each other, when so desired, by means of any two adjacent sides of the holder, as for instance, those sides joining at the corner 65, and generally will be spaced apart, as by an intercolated sheet of clear glass.

Means are provided for fixing the holder 24 to the face of the table 22 and in the present embodiment comprise movable clamps 61 variably positionable along undercut grooves 62 and maintained in the desired position by wing nuts 63 and the enlarged heads of bolts 64. By suitably positioning the clamps nearly any size of holder may be retained on the table and in substantially any position.

Forming an extension of one of the arms of the cradle 19, is a counter weight 67 which balances the cradle and eliminates any tendency of undesired rotation on the part of the table. As an additional means of maintaining the cradle in the desired position there is provided a threaded member 68 which may be turned by hand wheel 69 to press its rounded end into contact with the rear face of the table and thus hold it against rotation.

The cradle can be locked against rotation by means of pin 72 which seats in a recess formed in the periphery of the table. Pin 72 slides in a socket 73 formed in base 10 and from one side of the pin 7 2 there projects a smaller pin 74 through an elongated aperture in the socket. Pin 74 is received within slot 7 5 in lever 76 fixed to rod 78 which may be turned by handle 79 projecting pin 72 into a recess in the periphery of the table and holding the table, or withdrawing the pin and allowing the table to move freely.

A modified form of my invention is shown in Figs. 8 and 9, in which a base 80 provides upper and lower bearing surfaces 81 and 82' tending from hub 86. On each of these arms is slidably positioned a clamp 8? for rigidly retaining the reduced marginal portions 88 of a holder 89. Clamps 87 may be maintained in gripping relation with the holder by set screws 90, engaging with the arms 85.

Support 8% has pinned to it, on the other side of the support 83, a crank 91 by which the arms and holder 89 may be rotated about the horizontal axis formed by shaft 84% and between the crank and support is rigidly fixed on the shaft a pointer 92 cooperating with scale 94 stationary with respect to the support 8". For moving the support i its bearings 81, 82, to move the holcer about a vertical axis there is provided a handle 95 projecting out vardly from the support 83. On this handle in mounted a second pointer 96, which, together with scale 97 on base 80 serves to indicate the angular movement or position of the holder with reference to its vertical axis of movement or oscillation.

In both modifications it will be noted that I have provided means for moving or oscillating the holder about two separate axes at right angles to each other, the extent of such movement being indicated by the several pointers coo aerating with their respectire scales. In this manner, the holder can be made to assume any desired angle with reference to a light source, somewhat removed, and all desirable effects can be produced. By suitable manipulation of the several cranlzs, the holder can be variably positioned about each of its several axes, prior to the exposure to light of the elements or the holder may be oscillated or rotated about its several axes during such exposure, such movement, oi course, being determined by the subject at hand and the nature of the effect desired to be produced.
